I did it on my V2, and it was a bit tricky. And I had the bike half way apart already to make it a race bike. As some noted, you 100% for sure need to remove the upper and lower side fairings, and I think the front / nose, to do it. And then some of the other plastic stuff. The radiator is kind of an "assembly" on these bikes; with two radiators, a plastic casing thing that holds them together, and some other stuff. It's not as straight forward as most other bikes. I do remember having to fight the radiator and hoses and such a lot to get the radiator back in place. It's held on by these two small (m4 bolts) and (like all the other bolts that go in to this aluminum block), are very easy to cross thread and strip.
